I've never moved them before so we shall see how they do. I did notice they were planted pretty deep when we dug them. Maybe about 10 inches or so? I guess that is ok because they bloomed this summer before we dug them. I don't know what would make bulbs not bloom other than maybe not being planted the right depth? Are they accidentally being mowed off or sprayed with something? Really strange. I hope mine don't sulk!
